[announce] JackTrip packages for Ubuntu

[IOhannes m zmoelnig]

hi all,

Most of you do not know me (as I'm not very active in the JackTrip
community), however: as a Debian Developer I'm maintaining a couple of
multimedia related packages, among them "jacktrip".
So if you are running a Debian-based Linux distribution (e.g. Ubuntu,
Mint,...), and install JackTrip via a simple 'apt-get install jacktrip',
then you now know whom to thank for :facepalm:.


As explained in the past, I strive for keeping up-to-date with upstream
development, which means that typically new releases of JackTrip are
available in the Debian archives within two weeks¹.

However, due to the nature of release-based Linux distributions (like
Debian, or Ubuntu), this does not mean that the updated packages are
available for users right away.
Ubuntu releases every half year, so it can take up to 6 months until
people, who use the latest and greatest release of Ubuntu, will "see"
the new packages.
Alas! many users do not trust "the latest and greatest release of
Ubuntu", and instead stick with old and trusted LTS versions, which are
updated every other year. LTS gives you "enterprise grade stability",
and imho is targetted enterprises running servers and the like (as
opposed to: multimedia productions).
Debian has a release cycle of 2 years to begin with...
Now the very nature of release-based Linux distributions is, that the
software found in any given release is *frozen* (except for critical
bugs) at the time of the release.
So Ubuntu-18.04 is shipping software that is brand-new in spring 2018.
If your clock (like mine) keeps ticking, that means that in spring 2022
all software you will get from "Bionic Beaver (LTS)" is 4 years old (the
LTS means, that you don't have to worry about grave security bugs - at
least if you keep your system udpated).

Now people are (of course) ambiguous: they want super stable worry-free
systems (therefore they stick with their "16.04 (LTS)" Ubuntu from half
a decade ago), but at the same time want to have the latest and greatest
software that was released just 2 weeks ago.

Luckily, Ubuntu offers PPAs: additional repositories where you can get
newer versions of your favourite packages (at least: if somebody cares
enough to maintain them for you).



Since I already do the caring part for the Debian packages, I decided
(last night) to also create a PPA for JackTrip, so you can install the
latest and greatest version within reasonable time after a release with
a simple 'apt-get upgrade' and without the need to compile JackTrip
yourself.


Something like this should do the trick:

```
sudo add-apt-repository ppa:umlaeute/jacktrip
sudo apt-get update
sudo apt-get install jacktrip-gui
```

(if instead you want the command-line version of jacktrip only, use
`sudo apt-get install jacktrip` instead)

have fun.

¹ and *of-course* i missed the JackTrip-1.5.3 release, 1½ weeks ago.
i've just uploaded them now...

[Jane Wang]

hi IOhannes,

Thank you for your announcement and hard work!

I was wondering if there is a way to install specific previous versions of jacktrip and if so what the command lines would be for installing.

The reason I am asking is that in Sarah Weaver’s NowNet Arts Hub ensemble, members of the ensemble try to use the same version of jacktrip thru one concert season.  If a debian based participant joins the group after a newer jacktrip version is released, will that participant be able to install the same older version of jacktrip that the rest of the ensemble has?

Thanks much,

Jane Wang

ps, I wrote the RPi standalone guide that is currently on the jacktrip support website, three current ensemble members including myself use debian based rpi’s

afaict, PPAs automatically purge older releases (at least. I don't see
the 1.5.2 uploads any more), so i think the answer to your question is:
no, you can't have all the uploaded packages.

(i just asked on the irc, and this suspicion was confirmed).

is this
- based on some evidence that *newer* versions don't play well with
older versions
- or for instructional reasons ("now we all click the 'Enable Jitter
Buffer' toggle on the 'Jitter Buffer' tab..." - "Excuse me, I don't have
this toggle, but there's a 'Send Jiffies' button, should I click that
instead?")
- or just because of superstition (e.g. because some buggy *older*
version wouldn't play well (at all), and upgrading that to the same new
version as everybody else fixed it)?

(sorry if the questions sounds a bit rude, it's meant as a real question)

hi IOhannes.

this is wonderful!  thank you!

a couple of notes:

add-apt-repository wasn't on my system (Debian 11).  

i found the reference saying that it's in the software-properties-common package and successfully installed it per instructions with:

sudo apt install software-properties-common

the add-repository then ran -- but the apt-update ran with signing errors.

[Mike O'Connor]

pay no attention to the last bit (installing 1.5.1)  that's a quirk of the way i've got my system set up.  reading the output more carefully (in a larger font), my local 1.5.1 install is getting picked up rather than the standard 1.3.0 that was installed by apt.  my bad.

i don't really think that Debian integrates PPAs just as easy as Ubuntu.
i think that *typical* Ubuntu installations will come with the reequired
tools (i only tested on a minimal bionic Docker image, where they are
not included; but installing "software-properties-common" did the trick)

so afaict, most of your issues come from different expectations of
Ubuntu vs Debian.

you *might* want to file a bug against "software-properties-common" that
they should fix add-apt-repository to properly work the PPAs.

you could of course just import my key manually into your apt keyring.

hi IOhannes,

the idea of me, Mike The Village Idiot, filing a bug report against "software-properties-common" brings me to my knees with laughter. i wouldn't be able to answer a single question they might ask. ;-)

yeah, i think importing your public key will be the answer -- but (see "village idiot" above) how do i do that?

and yeah, i hand-loaded an image of 1.5.1 on that system and i put it in usr/local/bin which overrode the usr/bin/jacktrip that apt put there. sorry about that.

thanks,

mike

[Jane Wang]

hi IOhannes,

in answer to your question re the ensemble, here is my understanding of the reason why.

the reason the ensemble tries to maintain consistency in jacktrip versions is that the ensemble only meets twice a month in general, once to tech and rehearse and the second time tech, rehearse briefly and then perform.  the group is international and it is hard enough to find times when everyone can get together.  there are usually at least 16 ensemble members running on different systems and using different audio interfaces.  upgrading each time we meet to the latest version of jacktrip for everyone in the group many of whom are not comfortable with tech issues would be time consuming, painful (some members might not be able to do it in time) and leave probably no time to rehearse.  we also have different and new members joining each month.  if everyone is at least running the same version of jacktrip, that makes some of the tech a little smoother.  if its random what version of jacktrip someone is on who is having a tech issue, chasing down errors can get more complicated and time consuming.  I hope that makes sense.

I am wondering if in future the ensemble might be able to adopt a model wherein everyone has to try to have at least run a certain version of jacktrip and new joiners can use whatever the latest version is if they need to upgrade given that they might not be able to retrieve the same version of jacktrip that everyone else has.

Mike, perhaps this is already the case anyway, I am not sure (Mike has generously been donating his time and patience to helping ensemble members install and upgrade jacktrip, not a fun process).

Presumably whenever there is a major upgrade to jacktrip, the entire ensemble will have to do the upgrade.

Best, Jane

ps and yes as you mentioned, sometimes it is also that depending on what version of jacktrip you have, a certain command line option might not exist or possibly have a different label, etc

[Mike O'Connor]

i just stood up an Ubuntu 21.10 server on Linode

your instructions ran clean and installed 1.5.3

i then stood up a plain Debian 11 server (mine are customized a bit and could have caused the error)

instructions would need to include the steps to add the 'add-apt-repository' command (it's not in the base Debian 11 that Linode puts up)

i added the command.

i ran into a new error when adding the repository

root@localhost:~# sudo add-apt-repository ppa:umlaeute/jacktrip

no.
the errors you got originally were about `add-apt-repository` and some
tools it uses under the hood being deprecated by Debian¹ (but not by
Ubuntu, obviously).

that error seems easy enough to fix (just install 'gnupg') - which will
get you back to where you left with your initial attempt.

but anyhow, let me re-phrase: PPAs are for Ubuntu. They are *not* meant
to be consumed by Debian². So why do you think you should try?

IOhannes



¹ "apt-key" is deprecated as the warning in your original mail
explicitely says. i don't think that "add-apt-repository" itself is
deprecated - it's just that Debian does not endorse the liberal adding
of random repositories at all (see my initial email in the same vein).
The fact that the 'add-apt-repository' command is available in the first
place, is probably just a byproduct of keeping packages in sync between
Debian and downstream distributions.

² <arrogance>it seems that there's a plethora of blogposts out there
that describe how to use some randome PPA in Debian. I find the quality
of each of those that I looked at rather...poor. I think their is a
reason why nobody competent (that is: from Ubuntu, Debian, or both) has
written such a blogpost yet. So - while I think it is pretty easy to do
if you know what you are doing - I (not really being "competent" either)
don't think I *should* add another instruction set that people will
blindly follow to shoot themselves in their knees.</arrogance>

i see.
i guess i was trusting too much in the subject (which only mentions Ubuntu).

the proper way would be to put jacktrip into Debian backports[1].
you could create a "wishlist" bug in the Debian bugtracker that just
requests such a backport:
```
reportbug jacktrip
```

(there are a couple of questions, but i hope far less intimidating than
with software-properties-common)

gmfdsr
IOhannes

PS: just for the record: unlike with PPAs where it is easy to provide
packages for as old releases as bionic, i would not have *any* intention
of providing backports for anything else but Debian/stable (so:
currently that would mean, backports for Debian11/bullseye, but not for
Debian10/buster nor Debian9/stretch)

[Mike O'Connor]

hey you developers, if any of you are following this conversation. can you please do the 'reportbug' thing that IOhannes is talking about? i gave it a try and it failed because... it wants to Sendmail configured. the last time i ran Sendmail was... a long long long time ago, and i'm NOT going back there.

Roman! brilliant!

can you (or somebody) also keep an eye on this and update the documentation to tell us end-users how we can load it? right now the documentation points to apt install jacktrip, which will load 1.3.1. it then points people to the releases page for anything newer. it would be nice to have an explanation and a series of commands like the ones that IOhannes posted. here's the page i'm talkin' 'bout.
